Check if there is any damage to the circuit of the focus motor drive board.
14. Zoom Reset Error
Check if the position of the zoom mounting magnetic steel falls off or is damaged.
Check if there are other interference items in the zoom operating range.
Check if the zoom Hall elements is damaged.
Check if the zoom Hall elements is in poor contact with the lead of the PCB board or disconnected.
Check if the zoom motor is damaged.
Check if there is any damage to the circuit of the zoom motor drive board.
8. Troubleshooting
Following are a few common problems that may occur during operation. Here are some
suggestions for easy troubleshooting:
A. The unit does not work, no light and the fan does not work
1. Check the connect power and main fuse.
2. Measure the mains voltage on the main connector.
3. Check the power on LED to see if it can be light up or not.
B. Not responding to DMX controller
1. DMX LED should be on. If not, check DMX connectors, cables to see if they are linked properly.
2. If the DMX LED is on and no response to the channel, check the address settings and DMX
polarity.
3. If you have intermittent DMX signal problems, check the pins on connectors or on PCB of the
unit or the previous one.
4. Try to use another DMX controller.
5. Check to see if the DMX cables run near or run alongside to high voltage cables that may cause
damage or interference to DMX interface circuit.
C. One of the channels is not working well
1. The stepper motor might be damaged or the cable connected to the PCB is broken.
2. The motor’s drive IC on the PCB might be out of condition.
